HORSE HAY-RAKE.

SPECIFICATION formingpart of Letters Patent No. 261,545, dated July 25,1882.

Application filed December 10, 1881. (Model) To all whom it may concernBe it known that I, WILLIAM F. GOELLER, a citizen of the United States,residing at-Rock Falls, in the county of Whiteside and State ofIllinois, have invented certain new and useful Improvements in HorseHay-Rakes; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters orfigures of referencemarked thereon, which form a part of thisspecification.

My invention belongs to that class of horse hay-rakes usually termedself dumps, in which the draft of the horse is utilized in lifting therake-head to discharge the hay.

My improvements consist, first, of a novel and efficient means forclamping the rake-head to the hubs of the carrying-whee1s,'so that theonward revolution of the latter will rotate and thus lift the rake-headsufticientlyto discharge the hay; and, second, in providing a rest forthe teeth-cleaner, so that the same will not be affected by themiscellaneous shaking and liftin g of the several rake-teeth.

In the drawings, Figure 1 is an oblique plan view of a machine embodyingmy invention. Fig. 2 is an enlarged detached view of the devices usedfor unitin g. the rake-head to the carrying-wheels. Fig. 3, Sheet 2, isa cross-sectional view of the rake in a vertical plane, showing thelocation and operation of the system of levers.

A is the rake-head, and also the axle of the carrying-wheels B B, whichrevolve on the spindles C 0, attached to the opposite ends of therake-head A. 7 p

D l) are the ordinary thills.

E is the drivers seat.

F is a hand-lever, hinged at its rear end on the axle or rake-head A,andpivotedto the rear end of the movable fulcrum G, which latter ishinged at its front end on the crossbeam H of the thills D D. The leverF and fulcrum G are so located relatively to the cross beam H andrakehead A that when such lever and fulcrum are on the same planethatis, on a line between their respective hinged ends the rake-teeth W areheld down rigidly to their work, and it is impossible for the rake-headA to rotate in any degree. 7

Clips a a 011 the under side of the fulcrum G extend laterally under thelever F, and afford a stop and a rest for the latter when in the sameplane, as aforesaid, with the fulcrum G.

On the inner ends of the hubs II of the carrying-wheels B B are formedthe annular recesses or grooves K K.

Short cross-levers L L, used in pairs, as shown, Fig. 2, having theirlower ends hinged together, and having that portion of their lengthvbetween their point of crossing each other and their hinge aforesaidbent outwardly to conform to the convexity of the grooves K, cross eachother above the hubs I, and have their upper ends loosely resting in thegrooves b b of the interposed Wheels M M, rigidly fixed to each end ofthe transverse rod N.

The rod N is journaled in the upper ends of the short brackets O O O,which are fastened on the upper side of the rake-head A, and thus therod N is supported slightly above and be- .hind the axle A and paralleltherewith.

The outward crook of each pair of levers L L traverses and closelyencircles the grooves K K, and owing to the factthatsuch levers arehinged together below the huh I, and cross or pass each other above thehub I, as shown, it is obvious that any widening or separating of theirupper ends will cause such portions of thelevers as lie in the grooves KK to approach each other, and thereby clamp the hub I. This separation Iaccomplish as follows: A short lever, P, is rigidly attached to the rodN, extending for-ward in a nearly horizontalposition.

To the front end of the lever P is attached the ing rigidly affixed tothe rod N.v As the said plates have a greater diameter than the head T,there results between the plates at u an annular recess, which I havecalled the grooves, b b. The head T is made with its greater diameter ona line with the upper ends of the levers L L,

so that by the partial rotation of the rod N the head T forces the upperends of the levers L L apart. The front end of the lever S is placedwithin convenient reach of the drivers foot and provided with thetreadle c, and by pressing thereon the rear end of such lever iselevated, and through the medium of the chain RtheleverPdrawndownward.Bythismeans the rod N and its fixed head T are rotated forward, and thehead '1, acting as a double cam, widens the upper ends of the levers L Land clamps the lower ends of such levers upon the hubs I of thecarrying-wheels B so tightly that the onward revolutions of the hubs I Icarry with them the rake-head A. When the rake-head A has been liftedsufficiently high to discharge the hay the driver withdraws his foot andthe rake-head drops back to a working position by its own gravity.

It will be understood that the lifting mechanism described is applied toboth carryingwheels B B simultaneously.

In order to permit the rake-head A to rise, it is essential that thelock of the lever F and its fulcrum G be broken at the same time. This Iaccomplish by forming a lateral exten sion, 9, to the rear end of thelever S, which extends under the lever F at or near the point of itsfulcrum, and the pressing downward of the front end of the lever Sbefore mentioned to lock the rake-head to the hubs I I has the effect ofraising the rear end of such lever, and with it the lever L and itsfulcrum G, thus nn-.

locking the latter at the same time that the levers L L are locked tothe hubs I I, as aforesaid. lVhen in the rotating of the rake-head A thelever F has reached its perpendicular, it, in connection with itsfulcrum Gr, prevents any further rotation of the rake-head A.

In rakes as formerly made the cleaner V has usually been arranged torest on the back of the rake-teeth W, and as each tooth has its ownseparate action the cleaner is kept in the condition of continuallyclattering upon the backs of the teeth, which is not only unpleasant tohear, but results in racking and injuring the cleaner. To avoid this Iattach the hounds t i of the cleanerVpivotally to the outer ends,respectively, of the cross-head k, the latter being fastened to thefront side and near the top of the standard l of the drivers seat E. Bythis arrangement the hounds i i, when the rake is at work, rest upon thetransverse rod N and support the cleaner V so far above the raketeeth Wthat none of the latter, in their vertical spring, can strike thecleaner.

the rake-head A is raised the cleaner passes down the outside of theteeth W in the usual way.

In order that the drivers weight may assist in raising the rake-head, Iplace the standard I of the drivers seat forward on the cross-beam m ofthe thills D D and binge the rear ends of the thills D D to the frontside of the axle or rake-head A, so that the weight of the driver at therear end of the thills presses down upon the axle A forward of itscenter of motion, and serves in a measure to offset the like pressure ofthe rake-teeth back of such center of motion.

What I claim as my invention, and desire to secure by Letters Patent ofthe United States, 1s

1. The levers L L, hinged together at their lower ends and crossed abovetheir outward now, the hub I, and the rod N, provided with the groovedwheels M M, the latter containing each the cam-shaped head T,constructed and operating as and for the purpose described.

2. The wheels B B, having hubs I I, provided with the annular grooves KK, the levers L L, the rod N, provided with the lever P and heads T T,the chain R, and foot-lever S, in combination substantially as shown,and for the purpose mentioned.

3. The rake-head A, the rod N, having the plates u and heads T and leverP, the levers L L, wheels B, having the annular recesses K, and thefoot-lever S, in combination as shown, substantially, and. for thepurpose specified.

4. In a horse hay-rake, the levers L L, operated in pairs by havingtheir lower ends hinged together, and shaped to conform to the convexityof the hubs I, and being crossed upon each other above the hub I, andhaving their upper ends extending above the point of their mutualcrossing, in combination with interposed means whereby the levers can belocked or clamped upon the hubs I, substantially as shown, and for thepurpose described.

5. The combination of the lever S, provided with the lateral extensions9, the chain It, the lever P, rod N, provided with the wheels M M, thelevers L L, and the carrying-wheels B B, having the annular recesses Kin the hubs thereof, substantially as shown, and for the purposementioned.

6. The combination of the hounds i 6, crosshead k, standard Z, rod N,journaled in the upper ends of backwardly-extended brackets O O, rigidlyattached to axle A, and cleaner V, whereby the cleaner is positivelyheld clear of the rake-teeth until the dumping mechanism is set inoperation, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
